Statistical analysis of determined chromophore concentrations for ex vivo human atrial samples. All parameters were extracted simultaneously for each sample in the each of the four cohorts. The number of samples for each group was as follows: untreated LA (n = 34), untreated RA (n = 30), treated LA (n = 13), treated RA (n = 11). Bars are presented as mean and standard deviation.. Statistical significance with respect to LA_abl group: °(p<0.05), °°(p<0.001), °°°(p<0.0001); Statistical significance with respect to RA_abl group: *(p<0.05), **(p<0.001), ***(p<0.0001).
